Install Issues about retro

[onaclov2000]

Just wanting to document some install issues here too for others: I tried inserting this from the user guide but the roms arent installed:

import retro
env = retro.make(game='SonicTheHedgehog-Genesis', state='GreenHillZone.Act1')

Specifically this error returned (well last line)

FileNotFoundError: Game not found: SonicTheHedgehog-Genesis. Did you make sure to import the ROM?

I do see now (from the discord forum) that we need to go buy the roms from Steam, this is not obvious on the install instructions, I suspect a reference of that should be there.

Also where to place the roms would be nice to know, same directory?

Use the Steam downloader script, it puts the ROMs in the right place. Otherwise you need to use the import script manually.

retro will load roms you already own if they are stored in site-packages/retro/data/<game-title>/rom.md (i.e. .pyenv/versions/3.6.2/lib/python3.6/site-packages/retro/data/SonicAndKnuckles3-Genesis/rom.md)

what is the import script referred to above? why not just expose RETRO_DATA_PATH as an argument or readable from the env - or is that what this line is doing?

retro/src/data.cpp

Line 140 in 8a20c0f

const char* envDir = getenv("RETRO_DATA_PATH");

RETRO_DATA_PATH lets you swap out everything from site-packages/retro/data, but you still need <game-title>/rom.md folder structure. There is currently no way to have the ROMs loose and autodetected.

I am also having issues with the error in OPs original post.
gym_retro-0.5.3-cp35-cp35m-linux_x86_64.whl is not a supported wheel on this platform

I am running linux mint. Currently trying your fix, so far so good.

I've updated the documentation to specify the right version of pip to use.

I bought Sonic on Steam and installed it even though it said it was for Windows only (I run PopOS an Ubuntu variant). Right click on game name in library on Steam client. Look at properties then local files. There should be a Sega Classics folder with an uncompressed ROMs folder which has a file SONIC_W.68K. This file should be copied to a convenient location and renamed with file extension .md. Then run python3 -m retro.import /path/to/your/ROMs/directory/ Game gets imported and then you can run retro.make(game='SonicTheHedgehog-Genesis', state='GreenHillZone.Act1') in your python script and it should work.
